X-Git-Url: https://git.nubati.net/cgi-bin/gitweb.cgi?p=photo-tags.git;a=commitdiff_plain;h=22bd56c3686530b61c930e728eaade45ee17d9cc;ds=sidebyside

create thumbnails of all pictures at once, at limit option (-l) if we want to only create a certain number at a time

-l option might be useful in case the script will be run on a system where the resources are limited
